The 2019 Infiniti Q50 2.0L gets 25 MPG combined, a reasonable figure considering it’s a stylish, entry-level luxury sedan designed for a refined driving experience without costing too much. Fuel economy isn’t the main draw, performance and styling are more important. Q50 owners likely value a comfortable ride and distinctive look over maximizing fuel efficiency.

City and highway performance

The EPA estimates for the 2019 Infiniti Q50 2.0L are 23 MPG in the city and 30 MPG on the highway. In urban environments with stop-and-go traffic, the Q50’s performance is acceptable, but the turbocharged four-cylinder engine (compared to the available V6) has to work harder to move the car, which increases fuel consumption. On the highway, the Q50 achieves better efficiency, helped by its smooth-shifting seven-speed automatic transmission. Drivers who frequently commute long distances can expect results closer to 30 MPG, while those driving mostly in the city should expect around 23 MPG.

Annual fuel cost

The EPA estimates the 2019 Infiniti Q50 2.0L will cost $2,300 per year for fuel. This is based on 15,000 miles per year and national average fuel prices. Keep in mind that if you drive significantly more or less than 15,000 miles annually, or if local fuel prices are much higher or lower than the national average, your fuel costs will differ. The calculation assumes regular unleaded gasoline, something else to consider when planning your budget. You can find Q50 MPG across all years on this site.

Real-world expectations

EPA estimates are helpful, but real-world fuel economy often varies with driving habits, traffic, and how well the car is maintained. Hard acceleration, frequent heavy braking, and neglecting maintenance (like tire inflation and oil changes) will reduce fuel economy. On the other hand, smooth acceleration, anticipating traffic, and following the manufacturer’s maintenance recommendations can help you get closer to, or even slightly better than, the EPA estimates. The Q50’s onboard computer shows a running average of fuel economy, providing insights into your driving habits and their effect on fuel consumption.

How it compares

The 2019 Infiniti Q50 2.0L’s fuel economy is decent for its class, but some competitors are more efficient. For example, the 2019 BMW 330i gets 28 MPG combined, offering similar luxury with better gas mileage. The 2019 Acura TLX 2.4L gets 27 MPG combined and is another competitor that does better than the Q50. Even the Lexus IS 300 (RWD) gets a comparable 24 MPG in mixed driving, though its performance isn’t as much of a focus. Buyers willing to trade some luxury for better fuel economy might consider the Toyota Camry XLE, which gets an impressive 32 MPG combined. The Q50’s 25 MPG is in a competitive segment, reflecting that some buyers value styling or features more than they value saving money on gas. You can see all Infiniti fuel economy data here.

Tips to maximize efficiency

The Q50’s turbocharged engine requires a light touch on the accelerator. Avoid sudden acceleration and keep a consistent speed whenever possible. The engine’s power delivery makes it easy to drive efficiently without losing much performance. Watch the tachometer and shift up early for even better fuel consumption.

Proper tire inflation is important for fuel economy. Check your tire pressures regularly and inflate them to the recommended levels, found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Don’t inflate too much, as that can hurt ride quality. If you live where the temperature changes with the seasons, check tire pressure often.

Reduce idling. Modern engines, including the Q50’s 2.0L, use fuel even when stopped. If you’ll be stopped for more than a minute or two, think about turning off the engine. Idling uses fuel without moving you forward, reducing overall fuel economy.

Keep your car maintained. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine runs efficiently. Following the manufacturer’s maintenance schedule can prevent small problems from getting worse and affecting fuel economy.

Reduce extra weight in the car. Extra cargo adds weight, requiring more energy to accelerate and maintain speed. Remove unnecessary items from the trunk and passenger area to improve fuel economy, even if the effect is small. Every bit helps.
